Well I worked on it for another 25 mins and could not get the original GM belt back on.. (it was on there last week!!

)
So I ran down to AutoZone and bought a gatorback belt, the belts looked to be the same length when I compared them, but when I went to install the gator back it was slightly larger so I was able to slip it on from behind the waterpump...
This was the toughest part of the waterpump job (getting the belt back on!!)

P.s. the gator back belt at AutoZone was $17.99 I thought that was a good price, I have seen them as high as $40 in the past..
